These ruck-shafts at one end are provided with cranks E which are bent, so as to project into a groove Fin a cam-diskF, rigidly attached to the frame of the machine. As herein shown, the shaft E passes through i this cam-disk, the hub of the disk acting as a baaring therefor. The ends of the cranks are preferably provided with rollers E (See Fig. -5.) Connected with the rock-shafts ward. When againstarted in their'upward 6o .E are a series of teeth E, which may be of any desired construction and, as herein shown, are Wrapped about the shafts, one end of each tooth projecting outwardly, so as to engage the material, and the other end engag ing aholding-piece E These holding-pieces are rigidly clamped to .-the rock-shafts by clamps'E, so that the teeth are fixed upon the shafts. 'W-hen the shaft D is rotated, it

carries With it the -disks E and rock-shafts.

E. Such rock-shafts, because ofthe engagement of the cranks with thecam-slots of the cam F, are rocked during this rotation, so as members are preferably elastic and form a contracted throatw'ay, that is curved rearwardly and downwardly from the carrier-frame and then forward toward the axle of the QQJTYiIlge wheels, through which the material-isdelivered by the rotary rake. When the material is fed through this throatwayf-it is engaged h i a series of carrier-bars-H and I, which doff f e withdrawing-teeth of the rotary rakes. These carrier-bars are adapted to ,be re ciprocated and are divided into sets,fon c'set moving in one direction, while-the other. is moving in the oppositedirection. Said bars are provided with movable teeth J, which may be arranged in any desired manner. As herein shown, these teeth are pivotally connected to the bars and are each provided with a limiting device J which projects.

above the bars and limits Ythe movement of the teeth Withrelation-to the bars. When the bars are beingfmoyedupward, the teeth will be in theipositionshown-infull lines in Fig.3, and when they aremoved backward they slide over 'thefinaterial fandmove up out 'of the way, as shown'jin dotted lines in Fig. 3, so as not to'diraw thematerial backmovement, the teeth take their proper positions and carry .thematerial up with them. As herein shown, the. bars H are connected to the cross-pieces H, While the bars I are connected to the cross-pieces I. These bars slide upon the frame A and are preferably rod M with a crank M on a shaft M provided with-"limiting devices K."-whi'ch limit their outward -mov'ement due to the pressure of the material beneath them. .Tll

-cross-pieces I and H are preferably provided shaft D is provided with a crank M. This crank is connected by a connecting-piece or The shaft M is provided with rocking beams or bars M M fwhichware rocked each time the shaft D is rotated: It is of course evident that the connecting-rod M might be connected directly to the rocking bar M if desired. Attached to one end of the rocking bars are the connecting rods or'pieces N, which are fastened to the crpss-piece' I. At the other end of the rockinggbars are the connectingrods N, fastenedfito the cross-piece H. It Wlll thus be seen that when the shaft M is rocked lIl OIl ClllQCiQlOIl the carrier-bars I will be moved up and the carrier-bars H down, while when said shaft is rocked in the other direction the movement of the carrier-bars will be reversed. It will further be seen that by this construction these carrier-bars are reciprocated and that their movement is prace say, they are not lifted up and down, as would be the case, if they were connected with "cranks or eccentrics or the like, but, are moved backfie d; forth substantially in the. same planetit -wiill-further be seen that these carrier-bars project over the rotary rake, so as to take the material directly therefrom.

1 In the specification and, claims I have used the term hay as applied-to the loader; but

.Iyuse thissimply as a matter of convenience,

intending-itto' cover any and all other mate rial in connection with which it may be desired to use this device.

Theuse and operation of my invention are as followsiWhen the device is to beused, it is attached to the back of the vehicle into which the'materia'l is to be loaded. As the device moves along the shaft'D and the disk E are rotated, and the teeth Eengage the material and lift. it .up through the throat-' way, so that it may be engaged by the carrier-bars. While the device isoperating, the carrier-bars are reciprocating, one set moving in one direction and the other set moving in the opposite direction, so that atall times the doffing action may assist in cleaning the teeth E. 'As one set of carrier-bars moves up the teeth engage the material and move it up along the floor of the guideway. When it is moved u {a certain distance, it is engaged by anot er set of bars, which move it farther along, thejfirst set of bars being retracted and the teeth moving up against the tically a movement of translation-that is to .lbar so as to'p e rmit the free retraction thereof; This process is continued and the material th g moved up to'the point of discharge and "their; discharged into the vehicle. In this construction the reciprocating carrier-bars pro1ect over the throatway between the feeding device and the frame and carry the hay from said throatway ontothe guideway. It

further be noted that thebottom of the guideway is located above the feeding de the -floor "of the guideway in response to the pressure of the material.v If,

comparatively thin layer; but ifit is taken from --the-'windrow, this layer will be. much thicker and the carrier-bars will automat ically' move away from the floor to adjust themselves to this variation in the quantity of material. To facilitate this action, the" reciprocating bars are connected with the rocking-bar or other form of driving mechanism by flexible connections. The fact that the teeth of the feedin'gdevice are, as it were, flexible and tilt at the point of withdrawal makes it-possible for the teeth of the carrierbars, which are rigid during the forwarding -movement of] such bar, to effectively coopjerate with the teeth of the feeding device in disengaging the material't'herefrom. As will belnoted, the feeding device rotates in a di rection opposite to the feeding movement of the carrier-bars. The carrier-bars project beyond the frame at both ends when in their extreme positions. Theswath or .windrowof hay advancedugon and engaged by the and by its action and rotary rake is lifte 3 that of'the elevating device is moved upward and-forward; It may be saidto turn around travel by the elevating device.

the engaging members G and start in a forward direcg'on up the incline. The engaging .members curved as they 'are,-form on wall of the throat widely open belowan curved in the. direction, the mass is forced to The combination of elements forming the rakingand conveying device is also adaptable to that class of side-delivery hay-rakes in which the hay is lifted and afterward moved to position on an endless conveyer, which delivers it in the form of a swath at the side of the machine.
